【摘要】：隨著智能電網、智能家居的普及,將會有大量電氣設備通過網絡實現數據交換、信息共享和遠程接入,電力線通信PLC(Power Line Communication)技術將在其中發(fā)揮重要作用。PLC利用現有電力線,通過載波方法將模擬或數字信號進行傳輸,不需要重新架設網絡,只要有電線,就能進行數據傳遞。電力系統(tǒng)網絡需要對PLC設備進行有效的管理,這也將是本文的核心任務。本文的開發(fā)環(huán)境由Miineport和IT900兩個開發(fā)板及其配套軟件構成。Miineport是一個串口聯網模塊,IT900是電力線通信模塊,兩者之間用串口連接,并以Miineport作為主機,可以實現基于以太網接口的電力線通信設備。本文將設計實現該功能的系統(tǒng)軟件并給出具體的代碼,這些代碼編譯過后的可執(zhí)行文件通過以太網口 TFTP協議下載到Miineport中運行,Miineport通過串口控制IT900,進而控制電力線網絡。為了解決對電力線網絡設備的集中管理與維護,本文設計了適用于小型混合網絡的管理系統(tǒng),并給出了管理系統(tǒng)中使用的操作與相關指令格式。此外,在設計該系統(tǒng)時,還兼顧了電力行業(yè)現行傳輸規(guī)約,應用開發(fā)者可以在此基礎上實現具體的應用功能。最后在實驗室進行了組網與測試,利用實驗室現有的網絡設備,結合一系列測試軟件驗證整個電力線通信系統(tǒng)的功能。根據系統(tǒng)組網實驗,本文設計的電力線通信系統(tǒng)軟件能夠運用于中低壓配電網、接入網等實際網絡環(huán)境。系統(tǒng)實現了對電力線網絡中各個節(jié)點設備的管理與配置,主從設備之間可以進行簡單的自治,也可以通過局域網對整個電力線網絡進行管理。此外,系統(tǒng)也可以依據現行電力行業(yè)傳輸規(guī)約傳輸報文。
[Abstract]:With the popularity of smart grid and smart home, there will be a large number of electrical equipment to realize data exchange, information sharing and remote access through the network. Power Line Communication (PLC) technology will play an important role in it. PLC will make use of existing power lines. The analog or digital signal is transmitted by the carrier method, so it is not necessary to re-set up the network, as long as there is a wire, the data can be transmitted. Power system network needs effective management of PLC equipment, which will be the core task of this paper. The development environment of this paper is composed of two development boards, Miineport and IT900, and its supporting software. Miineport is a serial port networking module. It is a power line communication module. The interface between them is connected by serial port, and the Miineport is used as the host. Power line communication equipment based on Ethernet interface can be realized. In this paper, the system software to realize this function is designed and the specific code is given. The executable files compiled by these codes are downloaded to the Miineport via the Ethernet port TFTP protocol to run the Miineport to control IT900 through serial port, and then to control the power line network. In order to solve the problem of centralized management and maintenance of power line network equipment, this paper designs a management system suitable for small hybrid network, and gives the operation and related instruction format used in the management system. In addition, in the design of the system, the current transmission protocol of power industry is also taken into account, and the application developer can realize the specific application function on this basis. Finally, the network and test are carried out in the laboratory. The functions of the whole power line communication system are verified by using the existing network equipment and a series of test software. According to the system networking experiment, the power line communication system software designed in this paper can be applied to the medium and low voltage distribution network, access network and other practical network environment. The system realizes the management and configuration of each node equipment in the power line network. The master and slave equipment can be easily autonomous or the whole power line network can be managed through the local area network. In addition, the system can also transmit messages according to the current power industry transmission protocol.
